???? I think will be better take it to my mechanic. Thanks for trying to help but I don't understand what rpms means :-(
The gage in front of you.

One is MPH (left) and the RPM's (right)

When sitting at idle (no driving) the needle is around 600-700.

I'm thinking when you run the heat/Air cond. extra load (stress) is being put on the engine.

Maybe the jeep is shaking because it's hesitating or misfiring.
Basically it's about to stall.

Looking at that RPM gage. Is the needle bouncing around? Going lower than 500?

You possibly could have another problem.

If that's the case- if I can't help-someone on here can.

Just don't give money to a mechanic if it's something we can help you with or fix :)

Ok, I check the rpm and is like You said between 600 and 700. Never down 500. I notice when I stop on red lights the jeep its making a sound like suctioning something for a second.

Ok that's good.

I'm wondering if you may have a vacuum leak. Check all the hoses around the engine.
If you do have a leak it could cause the jeep to idle rough and shake like your describing.

That right there is a thing of beauty and what makes this board so great! Even though it's not about hot vibrations in the off topic section I'll check back just to see this resolved!
